Make premium, cutting‑edge, in‑demand products.

A breakthrough in performance, durability, and flexibility—a transformation to industry standards.

We license our eWindow technology to manufacturing partners, easily integrating into existing facilities, processes, and supply chains—and enabling the production of next-generation windows without sacrificing aesthetics or compromising on comfort.

Flexible Form

Designed to scale and curve beyond current technology limitations and frame sizes.

Animation of an opaque box, a semi-translucent box, and a clear box appear in order above a right-pointing arrow with 100% on the left and 0% on the right.

Uniform Tinting

Reliable, consistent switching over the entire window.

Ultimate Clarity

Ultra-low haze and reflection for optimum clarity.

Animation of multiple carbon dioxide diagrams moving from right to left. Each is a small clear dot, a large black dot, and a small clear dot connected in a horizontal line.

Eliminate Gigatons of CO₂

Increases building energy efficiency by 20%, and increases driving range by 10%.

30+ Year Product Lifespan

Proven to withstand 50,000 cycles at 1 Sun and 85°C.

“If we are going to solve the CO₂ problem, windows need to be part of the solution.”

Curtis Berlinguette
CEO

On a mission to deploy 10 million square feet of eWindows by 2028.

We are driven to create technology that actually reduces CO₂ emissions—not just claims to do so. The building blocks of our environments need to be more adaptable, and our team of designers and engineers are leading the pack.
